I assume the 2 errors are related.

Start by reproducing the failure on an RPi3 running LibreELEC: launch Netflix and click a profile. Collect the requested debug log and compare it with the two reported GetDirectory errors. Done means selecting any profile opens Netflix and displays playlists and categories without those errors.
